" i Application led August 26, 1922. Serial No. 584,453.

To all whom t may concern.' f i.

Be it known that I, JOHN;v T. Donrr a citizenV ofl Y- the United States, residing at Dundalk, in the county of Baltimore Aand State of Maryland, have invented a certain new and useful Improvement in Shoes, of

which the following.` is a full, clear, and exact description.

This invention relates to shoes, particu-V larly shoes for rolling mill workers. foundrymen and others who worlr` on heated 'floors or in a heated atmosphere.

One of the most serious discomforts to which such workmen are subjected is the eX- eessive heating of the feet. To protect their feet such worlnnen have heretofore worn heavy shoes with very thick soles. shoes. while they protect the feet to some extent.y have the disadvantage of` being clumsy. and also the disadvantage that when `they once become lheated they retain the heat and lbecome very uncomfortable. It is the main object of. this invention to provide a slice which will effectively protect the feet of the wearer against excessive heat. A further obieet is to provide a shoe which is heat resisting'` and at the same time light and comfortable. A further object is to provide. a heat resist-ing structure which is adapted to `he built up about any ordinary shoe.

T he following' description and annexed drawings set forth in detail certain means vmbodying` the invention, the disclosed means, however. constituting but one of the various mechanical forms in which the principle of the invention may be employed.

Reference should be had to the annexed drawings forming a part of this specification. in which Fin: 1 is a perspective view of the shoe: Fig. 2 is aside elevation thereof; Fie: 3 is a transverse section through the forward portion of the shoe.

Referrine to the drawings, I have shown a shoe of ordinary construction comprising an upper 11. to whieh'is secured the sole 12 and ieel 13. Secured to the sole 12 is anvauxiliary sole 14 which may be formed. from leather or from a heat resisting composition. The auxiliary sole 14 is `spacedfrom the outer sole 12 by means of a series of spaced trans- F The cleats 15 may be nailed to thc outer sole 12 and the auxiliary soie 14 may be nailed through the cleats 15 to the outer sole. The spaced `cleats 15 form air passages'bctween them, allowing;- free Such passage `of Vair between the outer and auxiliary soles.` The cleats 15 arcpreferably lformed of rubber or some other` resilient material in order to make the sole flexible and springy. lf desired, a layer 16 of asbestos or other heat resisting` material may be secured between the cleats 15 and the outer sole 12. An auxiliary vamp 17 is secured along its lower edges between the. sole 12 and upper 11 and extends from adjacent the front edge of the heel over the arch and toe of the shoe. The auxiliary vamp 17 lits loosely overthe body of the shoe so that an air space is provided between the shoe upper and the auxiliary vamp. kThe auxiliary vamp is slit centrally at the arch to provide edges which coliform to the edges of the lacing' flaps of the shoe, and lacing eyelets 18 secure the auxiliary vamp 17 to the upper 11 along the edges of the lacing flaps. The rear edges of the auxiliary vamp 17 extending from adjacent the forward edeje of the heel to the slit portion thereof are unattached so that air is free to circulate between the auxiliary vamp 17 and the upper 11 around the sides and over the toe thereof..y By reason of the free circulation of air between the outer and auxiliary soles 12 and 14 very little heat will be transmitted to the outer sole 12 with which the.

`foot of the wearer contacts. and by reasonA of the air space between the shoe upper 1l. and the auxiliary vamp 17 very little heat can be transmitted through the upper to the foot of the wearer.

Having described my invention, I claim 1. A shoe comprising` an upper and an outer sole, an auxiliary sole of flexible non- `metallic material said soles being` formed of A shoe comprising; an upper` an inner sole secured to said upper. an outer sole secured to said inner sole, a series of spaced cleats between said inner and outer soles. said soles and cleats being;` formed of materials which are poor conductors of heat, and a. layer of` asbestos between said cleats and inner sole.

A shoe comprising` an upper, a sole se cured to the upper, and an auxiliary vamp secured to said sole and overlying and spaced from the upper, said auxiliary vamp being unattached along its rear edge whereby air is free to circulate between the auxiliar \v vamp and shoe upper.

A shoe comprising` an upper, a sole secured-to the upper, and an auxiliary vamp covering the toe and arch portions of the shoe and spaced therefrom, said auxiliary rainp beingv secured-along its edges to the sole from adjacent the heel around the toe, the rear edges of said auxiliary yainp on opposite sides of the shoe being unattached whereby air is freeto circulate between said auxiliary vainp and shoe upper.

5. A shoe comprising an upper having lacing laps, a` sole secured to the upper, an auxiliary yainp secured. to said sole and over lying and spaced from the toe and arch p0rtions of said upper, said auxiliary ramp having` flaps corresponding to the flaps ol the upper, and lace receiving eyelets securing the flaps of the auxiliary vamp to the [laps of thev upper.

In testimony whereof, I hereunto alix my signature.

JOHN T. DORFI".
